The City Nature Challenge is an international effort to document nature in cities. The global event calls on current and aspiring community scientists, nature and science fans, and people of all ages and backgrounds to get outside and observe and submit pictures of wild plants, animals, and fungi during the Challenge dates in order to help scientists track real-time changes in our planet’s biodiversity and better understand wildlife conservation.
